摘要： 改进了以地表一维热平衡方程为基础的地表红外辐射场的理论模型，该模型考虑了具有不同地形的地表微元之间通过反射和透射等多种形式进行能量交换的物理过程.通过实测数据验证模型后发现，该模型模拟的地表温度比较合理.比较了由该模型和概率分布函数模型计算得到红外波段的辐射值，辐射能量结果基本一致；通过该模型的计算机模拟可以得到自然地表红外辐射场，可以反映辐射能量的空间分布.

Abstract: Based on the onedimensional energy equations of the terrain, the IR field model was improved to be able to take various processes of the heat exchange among different parts of terrain into consideration. It was proved that the distribution of the surface soil temperatures obtained by the improved model is suitable in comparison with the experimental value. The IR radiation distribution for the natural terrain was calculated and agreement on the results from the model of distribution function of probability.
